IP Trunks
IP trunks allow you to route voice and fax calls over Internet Protocol (IP)
networks such as the Internet and private intranets, reducing long-distance
charges and giving you added flexibility in routing traffic between sites. Both the
originating and destination switches must have the DEFINITY Internet Protocol
Trunk (DEFINITY IP Trunk) application or Lucent’s Internet Telephony
Server-Enterprise (ITS-E) Release 1.2. The DEFINITY IP Trunk feature consists
of the following components:
■ An IP Trunk circuit pack, which contains a Windows NT server
■ The DEFINITY IP Trunk software, which routes telephone calls and faxes
over the Internet or your company’s intranet
■ Configuration Manager software, which lets you administer the operation
and performance of DEFINITY IP Trunk service.
Both the IP trunk software and Configuration Manager reside on the Windows NT
server on the IP Trunk circuit pack. For information about Internet Telephony
Server-Enterprise, contact your Lucent representative.
NOTE:
DEFINITY BCS and GuestWorks do not support the full IP Solutions feature
of the DEFINITY ECS, only IP trunks.
Electronic Tandem Network
If your company requires a medium to large network spanning a large geographic
area, nationwide or even worldwide, Electronic Tandem Network is the answer. An
Electronic Tandem Network is a wide-area private network that tandems calls
through one or more systems to route the calls to their destinations.
An Electronic Tandem Network consists of tandem systems, inter-tandem tie
trunks that interconnect them, access or bypass trunks from tandem systems to
main systems, and the software and equipment to support call routing over the
trunking facilities. Different Electronic Tandem Network locations are connected
via analog or digital tie trunks. For example, a DS1 interface can act as a
high-speed (1.544 Mbps) digital backbone for voice and data communications
between Electronic Tandem Network locations.
An Electronic Tandem Network can be configured hierarchically. An Electronic
Tandem Network can connect individual systems; it can also connect other private
networks together.
Within an Electronic Tandem Network, each location is identified by a unique pri-
vate network location code, similar to the public network office codes that exist
within an area code. When accessing the Electronic Tandem Network, a user sim-
ply dials the network office code plus the desired extension number, for a total of
seven digits.
